Embroiled in a growing scandal about efforts to cover up the science on the threat posed by coal ash to North Carolinians' drinking water, Duke Energy is asking a court to hold a hearing to discover the source of a document leaked to the Associated Press.

In 2011, EPA produced — and subsequently buried — a draft report on fracking contamination at Pavillion, Wyoming. Now one of the authors of the original draft has co-published a review of the research in the independent journal Environmental Science & Technology. The new study, based on FOIA'd documents, links fracking and polluted wells.

The reports aren't released to the taxpayers who funded them but the Federation of American Scientists' Government Secrecy Project publishes leaked copies. Here are 17 of the latest, from air to water, food to fuel, and much more.

The U.S. Environmental Protection Agency's openness has been a major issue throughout the crisis of contaminated drinking water in Flint, which has caused lead poisoning of some children. One aspect of the openness issue is the ability of agency employees to speak with journalists; another is unfulfilled FOIA requests.

Water may be for fighting over, but water data is worth cheering about. A new Interior Department data portal may help journalists cover the ever-critical issue of water shortage and surplus in the Colorado River basin and nationwide.

If the water coming from your tap is unfit to drink, you have a right to know. But the crisis in Flint, Michigan, is challenging that assumption. Meanwhile, Michigan Gov. Rick Snyder (pictured) apologized to the residents of Flint, and "pledged to promptly release his emails about the issue," according to the New York Times.
